compared to placebo especially on INCONG trials (χ2 = 4.5, p<0.05), Fig. 1. Reduced accuracy under alcohol correlated with three measures of impulsivity: psychoticism scale of Eysenck’s Personality Questionnaire (r = −0.59, p<0.001), impulsivity scale on Eysenck’s Impulsiveness and Venturesomeness Scale (r = −0.54, p<0.02), and thrill and adventure seeking scale of Zuckerman Sensation Seeking Scale (r = −0.58, p<0.02), suggesting that alcohol may impair the ability to inhibit the prepotent but erroneous responses.
